Vintage Vincent Bach Corp 24W Tuba Sousaphone Mouthpiece Heavy

Hey Friends! Here's a Vintage Vincent Bach Corp. 24W Tuba Sousaphone Mouthpiece Heavy. I've had this since High School and just pulled it out of Storage. It's nice and clean with Natural Vintage Patina on the Silver. I'll let the buyer decide to polish it or not? I personally like the mouthpieces on my horns to have patina. Seems like they don't make 'em like this anymore! The bottom of the stem is not perfectly round but it fits well on a horn and didn't seem to make a difference in the sound or air flow... Make an offer... impeccable for everyday use. premium materials and excellent craftsmanship ensure long-lasting durability.
